I'm waiting for this answer too.

This is unclear to me. I removed all olive oil from my diet and use avocado oil exclusively in the rare circumstances that I need oil (such as making my own organic mayo or dressings or blackening my tuna steak). I have not dug into the research on olive oil yet because my avocado oil research indicated that it is better than olive oil nutritionally.

I would not say bad. I would say less good compared to avocado oil from what I know at this point. Spectrum good to bad looks approximately like this: avocado>coconut>olive>sunflower>cottonseed>soybean
